I just returned from an AZ vacation last night where I snapped some unusual Dodge Truck pix. They were in the "Ghost Town" abandoned Gold King Mine in Jerome, AZ.

The first shot is a 5 ton Dodge truck with a 413 CI flathead six equipped with dual carbs. A one year only model. The second shot is the big six.

The last two shots are also old Dodge Trucks,, but I didn't write down what year they were. Maybe someone else has an idea.

An interesting fact is that the mine town had a Studebaker repair shop right there near the mine. There were dozens of carcasses of old Studebakers right on the premises. Many Studebaker engines and parts were scattered about.

If you ever get to Arizona, take the time to visit the Ghost Town in Jerome.

I thought the biggest Mopar flathead six was the 309.3 in the 1928-30 Chrysler Imperials. Even the biggest flathead head Straight 8 was only 384.8 in the 31 thru 35 Imperials and high end Chryslers.
I could have sworn the biggest six in available in a Dodge in 54 was the 230.
Looking at the pics, it looks like a 230 with dual carbs. It doesn't appear larger in size than the 264.5 I have in my 54 Windsor Deluxe, think the sign may be a misprint.

Direct from Alpar:

Larger trucks used another family of in-line flathead six cylinder engines. There was a 331 cubic inch and a mammoth 413 cubic inch lugger was available in the T series and up. There may have been another engine in the 370 CID range, but I am not sure about that. The 331 was highly regarded in trucking circles as a durable, hard working engine. The 413 was equipped with two single barrel carburetors and had a very large appetite for gasoline. It was noted for twisting the drive sprocket off the end of the camshaft.

I want one.
I just wonder what a "large appetite" is, because the RB's couldn't be any worse, could they? I also think the 413 came with dual exhaust too. I once saw at a car show in Bellingham Wa, a truck, that had dual exhaust and two carbs, it was a flat head six, and was stock.

Ahh, I'm not so familiar with those, maybe I should spend a lil more time on Alpar! I'd never had the chance to get around too much of the large tonnage Dodges, I always wondered how they moved some of those larger loads, assumed it must have been geared like a bear!
TK: I bet they were torque monsters, for sure!
